The proposed Piñon Ridge uranium mill could be online in 2017


From the Cortez Journal (Jim Mimiaga):

The Pinon Ridge Mill has cleared several major permit hurdles and survived court challenges from environmental groups. Its proposed location is in Paradox Valley between Naturita and Bedrock off Colorado Highway 90…

Energy Fuels Resources Corp., a Canadian-based company with a main office in Littleton, Colo., has been working towards building the $150 million plant for the last six years. EF also owns the White Mesa Mill, south of Blanding, Utah, which is currently the only operating uranium mill in the country.

The new Pinon Ridge mill would process uranium ore using an acid leach process to produce yellowcake, a concentrated uranium product that is fabricated into fuel rods for nuclear reactors. The mill is expected to process 500 tons a day of uranium ore from re-opened mines on the Colorado Plateau, Uravan Mineral Belt, and Arizona Strip.

The Environmental Protection Agency has granted EF a permit for the construction of tailings impoundment and evaporation ponds. A radioactive materials license was approved by the Colorado Department of Public Health and Environment in April for the project…

The company still needs a construction permit from CDPHE before the project can break ground. Pending approval of permits, construction of the mill could be completed by early 2017. Public comments on the construction permit will be accepted. For more information go to
